Review of SCHOTT ZWIESEL Wine Glasses

I received these Schott Zwiesel Large Tumblers in a Coles/ Flybuys promotion. They are quite nice glasses, and Schott Zwiesel are known worldwide for their quality crystal glassware, which is used by many hotels, restaurants, winemakers and sommeliers. The glasses are known for their durability and are made of patented Titan crystal, which is shatter resistant and dishwasher safe.
